Color blocks and color tools

How do I edit a color block?

With a color block selected, you can see various formatting options on the right.

These options allow you to change the color, or make the color block transparent (slide the triangle under 'transparency').

Example: you can fill the color block with the same color as the sweater your grandfather is wearing, on the photo you have inserted below the color block. You can do this by selecting the color block you want to edit; next you click the icon with the pencil (eyedropper tool) in the right-hand column, and then you click your grandfather's sweater. Your color block will take on the same color as the sweater.
